New Jersey Gov. Chris Christie is accusing his Democratic opponent in the governor’s race of mocking his weight, calling it beneath the office of governor.

Speaking at a press conference on Tuesday in New Jersey, Christie, who recently had lap-band weight loss surgery, was asked about comments from State Sen. Barbara Buono at a campaign event.

“I think that it’s unfortunate that Sen. Buono has decided to go down the same path as Gov. [Jon] Corzine did in making comments derisively about my physical appearance,” Christie said, according to video from The Star-Ledger.

Buono made the comments in a speech that surfaced on YouTube last week, at a campaign event where she was criticizing Christie for making decisions to appeal to the national conservative base, rather than New Jersey. Slamming Christie for starring in a state-funded ad campaign to promote the Jersey Shore, she said: “Now I don’t know about you, but seeing Chris Christie frolicking on the beach is not going to drive me to go to the shore.”

Christie said her remarks were something he “put up with four years ago” when facing Corzine, and he would do the same now.

“The fact that someone running for governor would make derisive comments about someone’s physical appearance I think is really beneath the office she’s seeking, and I’m disappointed that she’s done it, but she’s playing out of the Corzine playbook in that way and many other ways, too,” Christie said.

The governor was referring to an ad by the Corzine campaign that said “Christie threw his weight around” when he was a U.S. attorney.

In a statement to The Star-Ledger, Buono’s campaign denied the remarks were about Christie’s weight, providing a definition of “frolic” and saying it implies someone who is “spry.”
